LED grow lights... input please.

I think the point of using LED's (for me at least) wouldnt be efficiency of growing bigass plants, but instead, the almost zero heat generated.

Imagine a set of 6 large speakers (the 2.5ft tall , bigass ones)

In the bottom, you have walls lined with LED lights, on every side, and a lowryder/lowlife in the middle. no vents required, just a burping everyday.

in the top 6"? an actual working speaker

if you get 1oz / plant, and have 6 speakers, you'll be getting two thirds of an ounce a week, enough for a light/weekend smoker, and a reasonable amount for a medical user.

its the perfect stealth setup, nobody would ever realise.

Yeah, too bad he had to do like everyone else as done, and wreck the experiment by putting in other lights. The people that need to do this are the people that either don't smoke weed or have plenty of weed, so they don't worry about yield and ruin the experiment.

I am not against LED lighting by any means, and I know that one day people all over the world will be trashing their other lights and switching to LED's. That day will be 6/12/0018.

Well dip me in shit and roll me in sugar.

Here's the best I've seen so far:

YouTube - LED vs. HPS 25 days into flowering

Or search youtube for "LED vs. HPS"

He did several videos at different stages, but this one is the last, and it's 25 days into flowering. Where is the results video?

But he has put a lot time and effort in his experiment...which I thought was well worth the look...He has spent some dollars as those lights are pricey...

I'm with Opie Yutts there. Almost all of the led grows I saw messed up at some point or the other. I was reading pages after pages of good info and then there is a CFL involved, early flowering, change in nutrients, a friend took over for holidays and let them die, one yanked them out being paranoid, HPS got introduced to save the yield, etc. I would have been happy to just hear that it takes 2 weeks more to have the same yield, or something like that. Still I hope people continue to do their grows, at some point there will be semi-scientific data.

Hey whatsup ladies and gentlemen, this is my first post over here. Nice to meet you folks and forgive me if you sometimes dont understand something on my posts, English is not my first language.

I've read very intesting information on this board, and this thread especifically has stuck me around and made me think about all this LED stuff.

It seems that the main goal of this thread has been testing the LED system as the only sourse of light to the plants. In my undestanding, it looks like the theory of provide only the wavelength used by the plants makes a pretty good sense, but so far, the LED system doesnt seem to be working very consistently by itself, based in the results shown by some folks over here. But what about a LED/HPS combo system? Somebody has tried it all the way?

I have my little garden inside a 2'x3' wardrobe running a 400W HPS setup, which gives me a great amount of light, but also gives me a big pain on the ass to control the temperature when the ligth is on.

I was wondering how my crop would perform if I change the 400w for a 150, maybe 250w HPS and add to the system something like 4 to 6 of those 168 LED bulbs, w/ more blue or red depending on the plants stage.

I pretty sure that a system w/ a 150wHPS plus 6 of those LED bulbs would cut the costs on energy by the half at least, as well as the temperature generated. Less and smaller fans would be necessary as well as less exhausting cicles.

If the goal w/ the LED is to drop down operational costs and provide a better and easier way to control the heat, a combo system like that would be a half way to the ideal situation. At least until the LED technology be better tested and developed to be used all alone.

I got no money right now to change my light setup, maybe in a month or two. Meanwhile, I'd love to read any information about this kind of setup. Does anybody have any data about it to share?

PEACE!

Hello and welcome to the forum. Thanks for your input.

I think that your idea is definitely doable. I would probably try 250W HPS from above, and then some bluish LED's around the sides. I think that if you spend enough money on the LED's the yields would be similar to your one 400W HPS. Please be sure to let us know how things work out if you decide to try LED's.

Are you German?

Here is a link to a grower on his 2nd try with the UFO, he got the maker to tweak one for him to start a 2nd grow using 70 Red/20 blue, and he currently has another experiment going on using the only competitor taking on the HID hut UFO. Granted they are using tomato plants or something but I was impressed he actually has the impressive grow log using several LED light kits.

oh looks like I was not the only one to find that site:) Did you order your UFO, I found out 2 days before Xmas they are totally out and the list runs into the first part of 2008

the above cited report - Experiments with Hydroponics, Aeroponics, and LED Grow Lighting - ends in part with this statement "im waiting for justin at HIDHUT to swap me out for a 70/20. i still believe this is a better mix...." apprerantly this is refering to a period earlier in the grow whereby he had some problems do to the lack of BLUE in the LED matrix. i did call Justin and asked him if his co. had obliged the greenpinelane.com researcher by producing the more balanced light requested. he responded by informing me that due to the input provided in this paper that the WHOLE line was tweaked to 70/20 with some changes made in the const of the UFO.

after throughly looking into this new product and looking at the DOZENS of pics, specs and charts provided by greenpinelane.com id have to reccomend the HID UFO tp all those intrested as just 2 of these in a 6x3 ft area would be more than enough to veg 6 plants. right now thier only looking at an "all around fixture" but in the future you can bet there will be - just as in HID lights - a spectrum for vegging and one for flowering.

i know the $$ is hard to swallow - especially when all you grow for is yourself but to those like me who grow for really sick people try to look at the upside:

1). MONEY - if you started growing more than a year ago you paid almost $200 for a HID ballast and if in your 2nd year youve already replaced your 1st bulb and if u bought a good one that was like $80 bucks - for a total of $160 now add an inexpensive reflector like an ECONOCOOL that was $150 - TOTAL is already $510 (and you still have to buy more bulbs every year)

2). ELECTRICITY - if your spending $300 a month in juice costs - that will go down to $50 bucks - over a year thats a $2500 savings (the cost of 4 UFOs and a few keggers of imported beer) AND remember thats just for lighting the lamps! dont forget the cost of

3). COOLING - the room during the summer and DEHUMIDIFYING (its these last 2 aspects that KEEP most cultivators out of the cycle during the summer months) ...not to mention electricity the added $$$ ...another EZ $100 a month

and i did also look at his end results and there were excellent

I'm tired of stats. Someone just make it so. And document it with photos.

I was most impressed with the photos and grow logs done on nearly all LED lights on the market and some not yet on the market. I am also guessing this experiment is rather reliable as HID HUT changed the light to this guys recommendations.

Crap I am looking at the buy it now button but I want to see how that new competitor LED grow turns out.

PS- I have no clue what I am talking about, but the guy seems to know how to get his stuff growing and his 2nd UFO test with the 70/20 just got going on 12-28, while his other one for .....oh hell check it out he is saying his plants under procyon 100 doubled in size in 4 days (UFO competitor)

this is the drawback although you can prepay and get to the top of the list by maybe offering to buy a large # along w some other equipment as did our coop when we also ordered ebb and flo systems

THESE WERE SOME OF THE FINAL WORDS BY THE RESEARCHER found at Untitled Page

Experiments with Hydroponics, Aeroponics, and LED Grow Lighting ...this report is complete Opie and i would highly reccomend that you review it as it also COMPARES the cloest competitors the PROCYON 100 (at $600 w a slightly more blue matrix) and the LED Grow-Master LGM5 PRO (which apprears to be vastly cheaper although you have to wire it yourself and not anywhere as powerful using 100s of smaller weaker LEDs on seperate grids)

Blossoming continues on the center and right tomato plants. The plants have gotten pretty large. Much larger than they are supposed to be as they are advertised to be 9-12 inches. These things are approaching two feet. They're very hefty with lots of vegetative growth. The Florida Petite and Florida Basket in the center and right are blossoming the most. The Red Robin has a few but still seems to be more in the vegetative state. I've shut off the blue bulbs for a while to see if the increased red ratio will have any effect on blossoms.

Plenty of blossoms are stil dropping without fruiting, but more and more are seeming to fruit. I don't necessarily think blossom drops are necessarily a light problem. There are thousands of other reasons for this inside of course. Hey, this is my first attempt with these particular tomato varieties and using the UFO for the first time.

Overall I'm pretty happy with the performance of this light. One thing the UFO can do for sure is grow big tomato plants. I'll continue to try different nutrient formulas for the blossoming stage. To tell you the truth, I'm not quite sure exactly what this'll take and the experiments will continue. Hopefully soon, the 70/20 Red to Blue UFO will arrive. I'm hoping I made the right guess. I'd like to see if I can avoid using extra blue bulbs and have a 100% UFO grow nest time.

as ive stated befor if you can endure the price this is it maybe next year the $$$ will come down....and all the pics a person could want are there as well

Thanks Ziggy, I've been watching that from nearly the beginning.

Tomatoes - Yes
Big Dank Nugs - Still not convinced

I read through this thread and I have yet to see any solid reasons why you would WANT to use L.E.D.'s??? :wtf: Anybody see any killer L.E.D. grows? They are inefficient, dim, and have to be almost touching the plant to have any real effect. Sure you could buy $3000 worth of L.E.D.'s and grow a plant or two, but whats the point? Thats a huge waste of money, and money = energy. I think the most efficient setup would use ether a Dual 600w Digital ballast HPS or a 1000w Digital ballast HPS.

I posted this in the an other L.E.D. thread: "I really don't think LED's are going anywhere, they are not even more efficient then a CFL for Lumen output per Watt used. Low pressure sodium would be the most efficient, but not for growing. So high pressure sodium would be the next step down in a efficient light source. Maybe sulfur plasma lights will get better/cheaper soon??

Here is some Lumen's per Watt:
Candle : ~.3 (Lm/W)
Incandescent : 20~24 (Lm/W)
Halogen : 30~36 (Lm/W)
L.E.D.'s : 26-70 (Lm/W) The high of 70 is for prototype white L.E.D.'s
CFL's : 45-105 (Lm/W)
Sulfur Plasma : ~100 (Lm/W) light output VERY close to sunlight, better than any other artificial light source.
Metal halide : 80~125 (Lm/W)
High pressure sodium lamps : 140-160 (Lm/W)
Low pressure sodium lamps : 180-200 (Lm/W)"

The 100 lm/W barrier has been broken by lot's of high power manufacturers for white LEDs last year (Cree/Luxeon/Seoul Semiconductor), available at stores.

I guess I wasn't up to date on prototype white L.E.D.'s. I looked around a bit and found the prototype white LED achieving 150 (Lm/W). The rating they gave it was VERY misleading. You might notice that it was rated using Lumen's per watt of light output, not per watt of electrical input. It was emitting 420 Lumen's at 8-watts. Witch is 52.5 (Lm/W) by my math. :wtf: They are trying to show some advancement, maybe to get some goverment funding?? Like wind and solar maybe???

Side note: The theoretical maximum is 683 (Lm/W).

Correct, at 555nm. Which is green. Which plants need less. That shows how much Lumens help in designing a plant-light :D

I have 14 of those 168 led red/blue mixed bulbs. They are bright, but at the cost of no lateral dispersion; a 5" round array expands to only 24" @ 10' (probably the 15° viewing angle version).
My first attempt was to make a flat grid with a 2.5" gap between staggered rows of bulbs; this was a failure as even 4' away only the area directly under the bulb/array was illuminated.
So I then remounted them so each bulb was touching the 6 adjacent ones; better but only the bulbs directly over the plant were contributing.
Next was an arcade so that the arrays on the sides could be directed at the plant itself; better but the end bulbs were wasted.

My final configuration was/is a cupola affair with 10 bulbs (1680 low power leds) focused on a single plant 5" away from the face of the arrays. There are 2 arrays pointed straight down and the other 8 are individually aimed at a specific spot on the plant and physically placed as close to the top 2 as possible. The entire plant is now well illuminated and flowering strongly, how dense the buds will be is anyone's guess.

To say that this low power led application is cost effective would be a sorry joke, but clearly it is possible even if it cannot be recommended.
Understand that I have the highest possible density of low power leds in 4 sq ft that are illuminating 1 sq ft, so it is also NOT space efficient.
Anyone wanting to use leds should look at the high power ones and bear in mind that commercial panels are far too weak for effective plant growth.

Hey brownthumb, welcome to the forum and thanks for your input. I'm really glad to get another LED grower in here. Any chance we could see some pictures? I am looking forward to final yield.

I have ejoyed this led thing and its something to do. Now think, if leds worked , industry would be doing it.
Industry wants the most light for the least cost. Industry wants the most light and lower replacment cost. Industry would stand to gain tillions of dollars saved. And industry still uses 48 in florsents, metal halide and hps.
Funny facts wind power, photo cells have yet to make ONE CENT. :yippee:The average loss is 14-25 cents per kwh. (thanks to the poor people trying to save money)(forget the inviromental problems)
Once again OHMS and WATTS wins, and the poor pay.
Note sky lab florsent lights, even they can not efford leds. They can, but not cost effective. Flat panel florsent lighting. Note they have a $10,000 a pound lift off weight cost:jumphappy:, even at that, its not cost effective. Mars systems cost are more and leds cant make it.
:S2:

Old news, man. The latest NASA groove here. :thumbsup:

(Couldn't edit anymore, but here what should be added to the post above:)

In addition: I don't have any of the problems NASA has to fight with. I have gravity, so hot air rises and cooling is much more easy therefor (let alone get rid heat in space at all). I get a parcel of LED for the same money I'd get a CFL delivered for. I don't have that limited space. I could build a 1Ã?1m panel. I bet in the ISS you have to beg for that amount of space big time or pay millions. 20 Luxeon Rebel high-power LEDs (all fitting on the SIM-card of your Mobile) are able to create 3600lm, I have a cool white CFL 4" here, 3350lm. NASA isn't the quickest sometimes, they often just have to depend on tested (aka old) stuff. Changing the lighting system in ISS isn't the same like at home. Again (if possible at all) millions of $ for the sockets alone (you mentioned the freight costs).

So I do see LEDs in (grow-)space very much so :D

Industry is doing it. The sign industry for one. There are many cities around the US and the world who have mandated that all electrical signage must be illuminated with non other than LED light. Coming soon to a city near you.

wow another like forum...brownthumb!!! another believer!!! check out mine man...im running 3 procyon 100s in a 2 x 8 closet...got 20 3 gal pots, 18 are jack herer x bubbleberry the rest are bag seed. 25 in all, got a few doubled up...love friday, high times article on the UFO is very good. the tests ive seen on green pine lane, by sfortier, show the procyon 100 to be awesome. he will gladly answer questions but DO NOT mention our favorite plant. he grew tomatoes and deosnt wish for any pot talk.please respect him guys, he's been very helpful for us on this LED endeavor. hopefully more of us will be starting this so we can revolutionize growing for us all.

peace and pot

Experiments with Hydroponics, Aeroponics, and LED Grow Lighting

this dude is SMART and on top of the LED issue and this forum is responded to by many LED industry wireheads who are on top of the whole game ..... lotsa tech stuff...LOTS of pics...lotsa spec

theres mention of both the high watt (100 rather than the single 14 OR 28W panels) LED products UFO and PROCYLON i suggest that all those who are posting here look at the site these dudes are posting to and rethink a lot of the stuff weve been considering and reasoning. after taking a look ck out what one of em passed on to me......out of his concern and our respect im not gonna name his (unless someday he wants to be famous).

as he is the UNKNOWN i still wanna thank him and give him his props

Ziggy,

I've spent some time looking over your forum from the link you provided.

These are my opinions, but please remember I'm just learning and have a long way to go. So, my comments are based on this and what I've found out by my testing which is all public for you to see. I could be wrong and reserve the right to be!

Anyway:

Forget about the small led bulbs and Ebay 14 watt panels like Flower Forcer, Grow-tec, HTG, etc They are not efficient nor powerful enough to do the job.

The Luxeon, Cree, LedEngin, etc, 1W - 15w high powers are the only way to succeed and are 30-100 times more powerful and much more efficient than the above.

The below is how I approach my grows. If I stick to these rules. I do well.

Because of my emphasis of controlling Blue/Red ratios, none of the lights sold are perfect yet for both stages. The UFO and Procyon are great foundations right now and have the power to do great things. However, if they had blue/red adjustments they would be much better. I'm finding I will need to suplement these lights with 3 watt High Power single red or blue bulbs as needed. The UFO tomato grow journal shows this theory working well and results quite quickly in the photos.

This is also the reason I am building my own high power light. I have a lot of controls built in.


Veg Stage:

Nutrients - grow formula

Lights: 18 Hours

I, and most of the knowledgable folks that correspond with me and others I can trust for honest opinions seem to be landing on a 1/3 ratio of LED to HID with pretty decent results. So far this ratio proves pretty good if not better than HID in the Vegetative stage only.

This means if you are challenging a 400 watt MH in a veg stage contest, you would need 125W of high power LEDS run efficiently, meaning the electronics are designed to run the LEDS at top performance and temperature controlled meaning the most LUMENS per watt.

Most important - The Blue to Red ratio is heavy in blue. This is the biggest mistake I see with LED growers. They are not using enough blue in the veg stage! Possibly 50/50 red/blue to start seeds and be at 60/40 - 75/25 red/blue at end of Veg Stage. It is important here to keep a balance of red/blue for fastest leaf/stem/root growth balance. Stretch control is your key. If too much stretch, your later success is doubtful.

My findings: Root growth suffers if not enough red. Stretch happens not enough blue. Leaves are too small if too much red. Leaves are to big if too much blue. Use these indicators to adjust blue-to-red ratios.

Blossom Stage:

Nutrients: Bloom formula.

Lights: 12 hours

This is most likely a 90/10 - 80/20 red/blue ratio. Red needs to be strong. Bring the blue down until all growth stops, but maintains good leaf and stem strength. You want minimal veg growth, but maintain good plant foundation. At this point, lower the blue to stress plant slightly. This should force blossom stage and if stressed properly, good blossom performance. Once number of blossoms are satisfactory, increase blue back to that point where plant leaves and stems get just healthy looking and strong. This should be about 90/10 - 85/15. This gives me best blossoms on every plant I have tried. However, there is need for improvement. Numbers of blossoms are there, but maturing them is another matter.

Opinion: Blossom stage still needs work, HPS is still better at the 1/3 LED/HID, but I believe from what I've seen, that a lot of bad blossom performance is being caused by stretched veg growth in every LED grow I've seen. You must pay attention to the veg stage to have a good blossom stage.

Future - I also think some orange and possibly some deeper blue will still need to be added, but some high powers in needed ranges have now just come available. I should be testing some of these shortly. a touch of UVB and some IR have not been ruled out and there are good scientific arguments that these are needed. This is proven by the fact that plant growth under the sun using tinted filtered UVB/IR glass is poor in the blossom stage.


now where to from here ???

one last thing if you post there dont say nothing about no ganja weed or shit like that ....lab coats

ziggy, dont know if you've seen, but im doing a grow right now with 25 plants and 3 procyon 100s

Its amazing how much credit NASA gets in so much credit for their "inventions". A majority of the time they have a need and other corporations create these technologies for them. Like mylar, created by the Dupont company(along with many others). Just ranting I guess. remember that anything in space was built by the lowest bidder:wtf:

Yeah wind & solar power don't work:postexcuseme:

people are living off of the grid just fine...

do u know how many wind turbine and how much solar and energy is sold back to utilities here in calfi....sayin it dont work dont make ya sound to 'telligent ya kno

So if the point im seeing here is to get the correct ammount of Red and Blue ratio during specific stages in the plants growth cycle, does this mean a grower would have to change to color scheme along with it? or would you be able to use the same set-up the entire grow. im sorry if this doesnt make sense im trying to grasp this whole LED concept.

Dodo

from what i read if you watch what your plants are doing (either streaching leaves too large or too small internode spacing) you can actually tweak your ratio and add whatever portion of the spectrum is needed to get maximum growth.

remember once upon a time there was only MH lamps available for indoor growth and look at how the industry has evolved. the author of the above cited report is now working on his own LED matrix BUT what hes doing is making it adjustable so that you can "dial up" what your plants need.

i would imagine like in all such ventures and taking into consideration the need to simplify for marketing and economic reasons, soon someone will develop 2 or possibly 4 different matrix - 2 seedlings and veg stages and 2 flowering stages one for onset to develop more flowering sites and to swell up the buds in the final stage

supposedly the 3 we are using say the red Nms vary. and the blues are set. they did to tests with "tomatoes" too. that was an amazing plant in and of itself...lol im happy with just getting equal yield. all the talk of stronger potency and some of the stuff in the High Times article this month, well....we will see huh. and hell yeah, i wish they would've made it adjustable somehow as far as the blue/red intensity at veg/flowering. we are using these lights all the way through, just changing the time at flowering.

and ziggy, your right on point as far as everything i've read as well. people are saying they wont work cause they were testing with cheap china panels. we have 3 procyons in a 2 x 8 closet...hopin for a hella harvest...lol

i dont know if id risk the entire crop the 1st time around. its not my grow BUT if it was id partition the last 2' of it hang jjust 1 PROCYON and then hang like 2 4ooW HPS lamps over the rest. it seems like - for now theres a lot of manipulation that you need to keep up on - from the report.

....'"Red needs to be strong. Bring the blue down until all growth stops, but maintains good leaf and stem strength....This should force blossom stage and if stressed properly, good blossom performance. Once number of blossoms are satisfactory, increase blue back to that point where plant leaves and stems get just healthy looking and strong.'".

the reasearcher closes his statement by giving this opinion.

.... '"Opinion: Blossom stage still needs work, HPS is still better at the 1/3 LED/HID, but I believe from what I've seen, that a lot of bad blossom performance is being caused by stretched veg growth in every LED grow I've seen. You must pay attention to the veg stage to have a good blossom stage.'".

this we can all understand with the new lights i would think that here what we need to do is make sure they are hung at the right height. refering back to the report at.... Untitled Page the reasearcher did construct a grid to evaluate lumen dispersion at not only reccomended height but several others as well. from looking at it one can see that the optimum is at 24". now i dont know about everyonelse but what we do is keep our babies short (2.5 - 3' tall) asa result if hung at 18" above the canopy most of the nectar part of the plant will be at maximum exposure thru out veg producing maximum results.

as far as claims of better faster bigger i know that will come. what the real concern here should be is power and cooling - i.e. if i can veg w 400w instead of 1200 and flower w 800w instead of 2400ive saved 2/3 on enegry in lighting and at least 75% in cooling and of those two cooling is what should be most considered and of the most importance. ya cant grow killer nugs unless you provide optimum environmental conditions for cannabis thats like 80 - 85 degrees lights on - and the most important 15 degree (or more) drop at lights out. do you have any idea how hard that is to do in july in calif? the NO HEAT LED is what will change the entire face of indoor horticulture.

Turtle420, Whats Up. I read in the start of your trhead that you were working with a lighting company great news!!! You might want to add to your list of(nm) from 400 to 480 Ultra Violet, and 520 to 560 green,( they do need alittle) 640 to 720 some yellow to orange, You already know about blue and red. You need a mixing board in the resister @ relay circuits, So you can fade your on coluor for veg @ flower in all your panel's. They have 10mm leds they sould be the brightest. Good luck with your project, Good research and development is always one giant step forward for the future in growing. Hey it takes Pioneer's to step out of the box and be willing to take chances in failure to make strives forward. Good Luck, Later

:thumbsup:It's great seeing all this interest in high power LEDs. When I started looking in the middle of last year there was very little to none. I believe with the long testing times and variables of lighting that we need as many collaborators as possible. My only caution on the adjustable lighting is during each separate test the ratio stays the same, one for veg and one for flower, ie. "10 days in to flower and there not flowering well, let me add this". Anything else would lead to confusion. After our first test is complete i'm thinking of adding dividers with diff. light ratios in each. However I'm not really capable of ordering individual LEDs and putting them together and I dont want any e-bay china lights. Supposedly HGL is going to put out a 14W cree do-it-yourself kit which would allow for some tinkering...gotta go check on the girls....

doughboy

P.S. anyone know where I can pick up a three month timemachine...lol

HI ALL, Ya'll need to go to http;//www.chauvetlighting.com and feel free to look at all the good light's. But on the Home page when the LDI 2007 BEST BIG BOOTH AWARD flashes click on the display, Wait for the real payer and watch the video and see the potintial and mix-ability you can get with the LED's. Later
